fastadmin 框架中图片点击放大

Posted 2020-12-16 wrld

fastadmin的原生图片预览,重新打开一个窗口太麻烦，使用layui做一个弹窗式的图片预览

1、将下面代码放在backend-init.js文件中

$(‘body‘).on(‘click‘, ‘[data-tips-image]‘, function () {
        var img = new Image();
        var imgWidth = this.getAttribute(‘data-width‘) || ‘480px‘;
        img.onload = function () {
            var $content = $(img).appendTo(‘body‘).css({background: ‘#fff‘, width: imgWidth, height: ‘auto‘});
            Layer.open({
                type: 1, area: imgWidth, title: false, closeBtn: 1,
                skin: ‘layui-layer-nobg‘, shadeClose: true, content: $content,
                end: function () {
                    $(img).remove();
                },
                success: function () {

                }
            });
        };
        img.onerror = function (e) {

        };
        img.src = this.getAttribute(‘data-tips-image‘) || this.src;
    });

　

2、页面的img标签中添加 data-tips-image，点击时自动弹出图片预览

　

<img src="{$goods.image}" data-tips-image  alt="">

3、以下是预览效果
